Alexander Zverev is set to replace Jannik Sinner as the men’s world number one after reaching the quarter-finals of the Vienna tournament.
The German player’s progress to the last eight means he will take the top position from Sinner at the earliest opportunity. The change in the rankings will follow Zverev’s run in Vienna.
Zverev’s quarter-final appearance is therefore significant beyond the tournament itself, as it secures his move to the summit of men’s tennis. Sinner is the player he will replace as number one.
